I had to take out the rear coat hanger things. The side pillar covers(rear's use a torx screwdriver)
The coat hangers are a PITA. iirc I had to twist them 45 degrees then pull them off.
You should be able to get access by doing that, but if you want to take the whole thing down you will need to remove all the side pillars and A pillars, as well as the front trip computer/sunglass holder compartment. Iirc the middle dome light will come down with the headliner, but check for screws holding it there.
I have an Access cab so double cab might be a little different.
